Application filed Match 1;9, 1912. Serial No. 684,774.

particularly to the monnting of the engine or motor in or upon the frame of the motorcycle, the object of the invention being t0 mount the mo-tor in the machine trame in such a manner that it may be rocked or svvung to one side or the other of the machine trame for giving access to the working parts of the engine, thereby greatly facilitating the work of repair and adjnstment and saving a great amonnt of time and annoyance.

liiam1factnrers of motorcycles, as a general plying the oil, lubricant, etc, so as to.

provide a certain amonnt of accessibility to the valves of the engine should they break or need replacement. With the swiveled suspension hereinafter described, a tank may be made of any suitable width without interfering With accessibility to the working parts of the engine.

It is freqnently necessary to grind the valves of an engine, requiring a special form of implement or screw driver which may be used for the purpose. VVith the present improvement, in view of the fact that the engine may be swnng to one side or the other, any ordinary screw-driver may be employed for the purpose or other impiement which may be readily carried in the tool bag on the machine.

Sho-uld the replacement of the valves be necessary on the road, this may be accomplished without the removal of the engine from the frame.

In most air cooled engines, such as are used on motorcyoles, the employment of heavy lubricating oil results in the deposits of carbon in large quantities on the head of the cylinder and the valves and under the present mounting of these angines, it is necessary to move the entire motor from the machine to remove the oarbon. As this is necessary for about every five hnndred miles of travel of the machine, the work of cleaning out the carbon becomes very ardnous and annoying; B-y means of the present inventien all these parts may be readily, gotten at by a simple'operation which Will require only a fevv minutes. It is also feasible to replace a broken piston ring in a very short space of time and shonld it be neccssary to remove the motor from the machine this can be accomplished in a very small part et the time hertofore reqnired. in fact, the operation'of renewing and repairing the Working parts of the engine is so facilitated -by this invention that there is, no tendency for the operator to continue using the machine when the motor is badly carbonized or when one of the piston rings has b ecome broken and is, thereiore,, fiable to score the cylinder; 7

With the above and other objects in view, the invention c0nssts in the construction, combination and arrangement of parts, set forth in and falling within the scope of the appended claims.

In the accompanying drawings;Figure 1 is a side elevation, partly in Section, of a sufficient portion of a motorcycle to illustrate the application of the present invention thereto. Fig. 2 is an end view of the same, shovving by dotted lines the manner et rocking or tilting the engine to one side. Fig. 3 is a detail vertical cross section through one of the trunnions and trnnDion seats. Fig. 4 is a detail vertical cross section, showing the means for locking the mo-tor to the frame.

Referring tothe drawings, 1 designates the drop frame of the motorcycle having monnted therein a motor embodying the crank case and cylinder 3.

In carrving out the present invention, tronnion blocks 4 are monnted at opposite places and are designed to receive trnnnions 5 projecting from the crank case 2 at diametrically opposite places, as shown in Fig. 1.

Each trunnion bloek 4: is provided with a snbstantially U-shaped scat 6 for the adjacent trunnion 5, said seat being open at the top, as best illustrated in Fig. 3 to admit of the ready insertion and removal of the trunnion.

7 designates a threaded boit Which passes through the trunnion bloek and the frame 1, the inner extremity thereof being received in a threaded opening 8 in the adjacent trunnion 5. The boit 7 is provided at its outer end with a sqnared head 9 adapting it .toloe turhed by means of a wrench or pliers and when adjusted to its proper position, this boit 7 is held by means of a swing nnt 10 either with or without a spring split washer 11 which prevents the nut 10 from turning off the bolt 7. The oppositely located bolts 7 may beremoved or partially removed to admit of the removal of the trunnions 5 from the trunnion seats 6 in an npward direction, In view of the fact, hOWeVer, that the trnnnions rest in the seats onth blocks 4, there is no strain on. the bolts 7 which merelyserve, therefore, as retainers to prevent dislodgment of the motor under the conditions presented by road work.

In order to look the motor, in its working position, the crank case is provided at the bottom with a pendent lug 12 which is internally. threaded to receive a screw plug 13 having a projecting head 14 at its lower end which head forms a shoulderjagainst which bears a fiange of a union 15.

Extending aronnd the bottom portion of the frame 1 is a fixed sleeve 16 projecting upward from which is a threaded stnd 17 7 npon which the union 15 screws as shown in Fig. 4. When the parts are secnred together, as shown in Fig. 4, the motor, as a whole, is held in fixed working position. In order to tiltthe motor to one side or the other, it is only necessary to unscrew the Union 15 after which, by unconpling the mutile pipe and control rode or wires, the motor is free to be swung to one side for the purposes of adjnstment or replacement of any parts. The motor may be entirely removedby withdrawing the inner ends of the bolts 7 from engagement with the trannio-ns'5. After all the parts directly connected with the motor have been detached, the motor may be liitted easily ont 01: the frame as it is then only supported by the trnnnion blocks. The motor may be re- Copies of this patent may be obtained for stored to its operative position in the same manner.

' I claim:

1. In a motor cycle, the combination with the machine trame, of a motor provided with trnnnions, trnnnion seats on said trame having an open side t0 admit the trunnions, bolts on the frame movable into and out of engagement with the trnnnions, and means for locking the motor in fixed relation to the frame.

2. In a motor cycle, the combination with the machine frame, of a motor provided with trunnions, trunnion seats on said frame having open sides to admit the trunnions, bolts on the frame movable into and ont 01" engagement with the trunnions, and a threaded union for locking the motor in fixed relation to the frame.

,3. In a motor cycle, the combination with the machine trame, of a motor provided with trunnicns, trunnion seats on said frame having open sides to admit the trunnions, and means for locking the motor to the frame embodying a rotatable union and a threaded extension adapted to be engaged by said union and forming a direct connection between the motor and the motor cycle frame.

4. In a motoreycle, the combination with the machine frame and motor, of trunnions on one of said elements, trunnion seats open at one side on the other element permitting the motor to be swung on a fore and aft axis without removal from the machine trame, and means for retaining the trunnions in their seats and releasing the same to admit of the removal of the motor from the frame.

In testimony whereof I afiix my signature in presence of two witnesses.
